I voted other thinking of BHop, his win over Trinidad was sensational as was his dominance in the Middleweight division. I place Mayweather in the same ball park as BHop but I don't think Mayweather has a win as good as Trinidad.

That being said I think fighter of the decade awards are pointless/misleading in the sense that they favour fighters who put in work towards the end of the decade as opposed to fighter who were consistent and then waned towards the end of the decade or fighter who put in work at the start of the decade.
